My friend and are dating twins

If I have to give U answer in one line then I would say there is nothing different in dating a twin. The girl which I am dating has a twin sister. They are good friends. “I used to date a girl with an identical same sex twin. Most people couldn't tell the difference between them, and couldn't understand why I was. My friend went on to marry twin in question and they had similar problems. When I started dating my ex, her sister was the hot one, by the end.
